Abstract

302,928. I. G. Farbenindustrie Akt.- Ges. Dec. 23, 1927, [Convention date]. Addition to 282,409. Anthraquinone dyes.-Acid wool dyes are made by causing a 4-halogen-1-aminoanthraquinone-2- sulphonic acid to react with a monoacyl compound of the m-phenylenediamine series containing an alkyl group in the acylamino group. In an example, sodium 1-amino-4-brom-anthraquinone- 2-sulphonate is heated with m-amino-methylacetanilide in the presence of sodium bicarbonate and copper sulphate solution; the product dissolves in water to a blue solution. The m-aminomethylacetanilide may be replaced by the corresponding bases which are ethylated in the acylamino group. Specification 294,986 is referred to. m - Aminomethylacetanilide is obtained by acetylation and methylation of m-nitraniline and subsequent reduction of the nitro group. The other acylatad and alkylated derivatives of mphenylenadiamine are similarly prepaped from mnitraniline. The Specification as open to inspection under Sect. 91 (3) (a) comprises also the use of monoacylated m-phrenylenediamine derivatives containing aralkyl or hydroaromatic residues in the acylamino group. This subject-matter does not appear in the Specification as accepted.
